Based on the analysis of the development trend of intelligent ships and management mode of ships’ entry and exit of port，we propose the construction conception for the corresponding ship-shore interaction system，i.e. port shore-based auxiliary system. The needs of shore-based construction is put forward according to the characteristics of intelligent ships. The information sharing mode is proposed considering the management mode of port，maritime affairs，pilotage，etc. The needs of auxiliary berthing construction is put forward for the berthing and departure operations. The supervision requirements for the ship-shore interaction is presented for the operation mode of intelligent ships. Based on the existing infrastructure of the port，we adopt the communication network and perception network，add part of the sensors，information data processing system and cloud platform to build a shore-based system for intelligent ships entry and exit operations. This idea is of great significance for improving the efficiency of port operation and enhancing the throughput capacity of the navigation channel.
